Sounds Great

The following review is for C2-400X, which is a part of the bundle you are viewing.

Just put in a pair of the JL Audio C2-400X into the dash of my 2000 Porsche Boxster S. and they sound great! I cut the old speakers out to make a mounting bracket. And that work. Overall Sonic Electronix was easy to order from and the speakers sound great.

Quality Item

The following review is for C2-400X, which is a part of the bundle you are viewing.

After fitting a JL Audio amp & speakers to my Jaguar XKE I added the JL C2 400x to the front console area which is limited in space, the JL's perform beyond their size & price! Sonic Electronix dispatched quickly & efficiently, good service, would definitely use Sonic again

Easy to use and apply

The following review is for CSM, which is a part of the bundle you are viewing.

I used this product in my rear component speakers (Alpines) for the mid-range woofers in the doors to shield against vibration and they do a good job and the speakers sound great for it!
